Depression

anti-depressant (noun) : the pill that keeps one optimistic about one's life

Of course, after common unhappiness comes depression. Some embrace it alone, simply as a fact of life; others drag everyone around down with them as a part of life.

Freud believed that depression involved loss and the guilt and self-criticism related to that loss, but that doesn't explain all types and forms of depression. (And since his goal was simply "common unhappiness" - a concept depressing in itself - I'm not sure how much weight I give to this.)

Speaking of depressing, I read a great quote about the unexamined life - although it might not be worth living, the examination itself might take the place of living.

Now if that's not enough to stop therapy, I don't know what is.
